Very interested in this development! How is the interface between the X86 and Arduino parts realised? My application would require pin activity on the Arduino pins to be available as an interrupt to the X86-based program with minimum delay (max 10usec). For IDE compatibility I'm assuming the interface has to be a serial emulation but how fast can it work? Perhaps there is more than one interface? Thanks. John.
Hi there @G3WGV. and welcome in the UDOO community! We've tested the internal UART serial up to baudrate 921.600 We've still to test the latency.
Hi Andrea, Thanks for the information. Latency/driver efficiency will be the key issue. On the Arduino Due, for example, you can set the programming port baud rate to 115200 but you can't get anything like 11520 chars per second down it using standard I/O. Assuming that's the only interface then it might be better to fit an Ethernet card to the Arduino side and pass traffic that way, perhaps as UDP, which is what I do with the Due. Something to experiment with when I can get one! John.
